I feed live, RESTRAINED rats to MOST of my balls, and I have NEVER had a problem, and probably NEVER will. I know that there are snake owners out there who like to watch 'the kill' for personal enjoyment, and to have their perverse need to watch death satisfied. I am not one of them. I feed live because most of the 'Big Breeders' that I have purchased my snakes from had been feeding them live. As a sidenote, in the "Ball python breeding video" by Dr. Mark Seward and the Sutherlands, Collette is shown feeding her balls live rats. Why don't you e-mail her with your feelings?
BTW, I'm wearing a fire-retardent suit, so FLAME AWAY!!!!!
